HUGO JOSEF, OF CLEVELAND, OHIO.

VENTILATOR.

Application filed June 2S, 1923.

l 1o all whom t may concern.'

Be it known that I, HUGO JOSEF, a citizen of Austria, residing atCleveland, in the county of Cuyahoga and State of Ohio, have inventedcertain new and useful Improvements in Ventilators, of which thefollowing is a specification:

The present invention relates to certain new anduseful improvements inventilators for buildings and like structures and has .for its object toprovide a device of this character which embodies novel features ofconstr-uction, whereby a supply of fresh aircan be obtained within abuilding without the necessity of opening any of the usual doors orwindows.

The invention also aims to provide a ventilat-ing device which can beregulated by .the occ-upant of the building to control the quantity offresh air entering the building, and which will supply fresh air withoutletting in rain or snow in stormy weather.

Further objects of the invention are to provide a ventilating devicewhich iscoinparatively simple and inexpensive in its construction, w ichcan bereadily installed in a building, and which is at all times underthe erfect control of the occupant of the built ing.

With the above and other objects in view,

the invention consists in certain combimovable panel which normallycloses the.

outer end of the ventilator opening.

Figures 1l and 12 are detail views of the connecting bar for causingthe' two sets of shutters to operate in unison when the elec- 'tric fanis not in use.

Corresponding and like parts are referred to throughout Vthe followingdescription and on Vall .of the views of the drawings by like referencecharacters. v

The ventilator is adapted'to be installed in the wall of a building orlike structure and provides an effective means for per mitting fresh airto enter the buildingwithout the necessity of leaving any doors orwindows open. This makes it possible to properly ventilate the buildingin stormy weather without permitting the entrance of rain or snow intothe building, and the building can also be properly ventilatedwith allof the doors and windows closed and locked, so that unauthorized 'entryinto the building is difiicult and can only be accomplished by breakingopen some part of the building. j The ventilatingopening A is formed ina frame B which is built into a wall of the building and which may be ofany suitable construction, As indicated in aA general obvious, however,that when the arms 3 are y Vswung inwardly and disengaged `froin the Wayby Figure 3, the frame B may be at ythe upper portion of a` casing Cwithin which the windows D are mounted, although this is not material oressential to the in-V vention and the Ventilating opening can be formedVin the wall of thebuilding in any suitable manner. Y Y

The Ventilating opening in the present instance is horizontally disposedand of anV elongated formation, and the outer end of from the frame B.The slats in the 'outer panel thus tend to prevent rain or lsnow fromentering the opening with the 'supply of fresh air, while the lslatsofthe Vinner panel serve to direct the fresh air down wardly as itenters the building.

The outer panel E is provided at the four corners thereof with swingingarms 3 which are hinged'to the panel at l. The swinging ends of the armshave notched portions which' are adapted to engage lugs 5 secured to thetop and bottom walls respectively of .the ventilatin-g opening forthepurpose of securing the panel in'position. It will be lugs the paneleanjbe bodily removed from position. rlfheinner panel F may be locked'in' position in any suitable manner, although foi-illustrative purposesone end thereof is sho-wn as provided:with ,longitudinally extendingpins 6- which are adapted to enter corresponding openings in the frame,while the. other end of the panel is provi-ded with a lconventional keycontrolled lock 7'. `When the bolt of the lool: isjretracted thecorresponding end of the panel can be pulled out ofthe fra-ine afterwhich the panel can be given a longitudinal movement to disengage sthe-'pins' 6 from the sockets or openings.

outer panel E. is provided with a piecev of screening or woven wirefabric 8 which .Y extend-'s asi-oss the openings thereof, softha-t Y theentranceof insects or largey particles of v foreign matter into the'ventilating' opening is prevented. The back of the outer panel is also*provided withv a series of lshutters 9; shownonthe drawing, there aretwo sets' of the shutters 91, each set con-taining three' shuttersandthe shutters being arreleasing the ranged in an end' to end relation.Each of thel shutters is provided at the ends thereof withrpivot studs10 which` engage bearings 11, and by swingingthe shutters into Van openor a closed'positionthe ventilation can be controlled." rlhe'swingingedges of the Y shutters are provided with arms 12, and the arnisrof theYtwo setsk of Vshutters are connected by the bars 13 and 13V so that theshutters of cach set can be operated in unison. Y

The control bar 13 for one'set of the shutters is connected at its lowerend to a crank arm 14 on a rock shaft 15 which is journaledinsuitablebearings 16 on the lower edge of the panel. VrEhe end of therock shaft is provided,witlia crank portion 17 which env gages arslot1311i a plate'19 which is secured.A Y

Vtothe upper end of a reci'procatiiigrod'2O. A coil spring 21 1sconnected to the plate 19 and normally ytends to draw it. upwardly andclose the shutters; VItwill be obvious,

however, that byV movingthe Vrod 2O VVand plate 19 downwardly the`rock'shaft 15 will be rotated tov open the' shutters and the amountofventilation which is obtained is controlled by the degree to whichtheshutters are' opened. The slii'i-tters may beeither partially orcompletely opened andthe ventilatioii of the building is thus entirelyunder the control ofthe occupant.

'The control rod 20` extends downwardly through a vsuitable passageinone. side Vof the casing C, and` has the lower 'end' thereof Yconnectedtfo a slide 22`w-hicli is mountedV in a frame 23.

','The roundedV nose of theV spring actuated pawl interlockswith 'the notches to prevent acl Y cidental movement of the slide bar,although the slide bar can-be forcibly moved when it is desired tochange` the adjustmentthereof.

-Whenso desired the two sets ofshutters can be connected so that theyoperate in unison, and are bothcontrolled by the handle 26. Forthispurpose two of the shutters 9 which Ahave an end to end rela.- tionare connected by a bar 35, such as is shown by Figure 11. Thisconnecting bar 35 may have the middle portion thereof arched, so thatVit will straddle the bearings 11, and the ends thereof are detachablysecured to the respective shutters so that the shutters will operate inunison. The shutters of each set are operatively connected by the arms12 and control bars 13 and 13a, so that when the connecting bar 35 is inplace the two sets of shutters will move in unison and be bothcontrolled by the single handle 26. The connecting bar 35, however, canbe readily removed when it is desired to provide a separate controldevice for each set of the shutters.

Under some conditions it may be found desirable to associate an electricfan with one set of the shutters so that a forced circulation of air canbe obtained. For this purpose a fan housing 33 may be suitablypositioned within the ventilating opening and a suitableelectric fan 34mounted therein. The fan may be controlled by a conventional electricswitch 37, which is shown on Figure 3 of the drawings as mounted uponone side of the casing C, just above the plate 27 of the mechanicalcontrol device for the shutters. The wires 33 for the electric fan leadto this switch 37, and a pair of solenoids are interposed in the fancircuit, so that they will be energized when the fan is ruiming. Thesesolenoids are mounted upon a shelf 40 which projects upon one side ofthe fan housingT 33, and an armature 41, is arranged above thevsolenoidsso as to beV drawn downwardly thereby when the solenoids are energized.A stem 42, which is rigid with the armature 41, is slidably mountedwithin the shalf 4() and a guide member'V 43 which projects from a sideof the fan housing' at a point above the solenoids. The lower end of thestem 42 is provided with a forwardly projecting plate 44 which has aslot 45 therein, said slotreceiving a pin 4G on the control bar 13a ofone set of the shutters. A coil spring 47 which is connected to theupper end of the said control bar normally tends to hold the shutters ina closed position.

The connecting bar 35 for causing the two sets of shutters to operate inunison is, of course, removed when the fan device is used. The fandevice can be readily installed in the' casing, and it will be obviousthat when the switch 3T is open and the fan at rest the' shutters willbe held in a closed position by the coil spring 47. lhen the switch isclosed to put .the fan into operation the solenoids 39 are energized andthe armature 41 drawnfdownwardly thereby. This moves the stem 42 and theslotted plate 44 downwardly, with the result that the control bar 13a ismoved downwardly and inwardly to open the shutters. The shutters arethus automatically opened as an incident to putting the fan intooperation, and in a like manner the shutters are automatically closedwhen the fan is stopped.

A ventilator of this character enables an abundant supply of fresh airto be introduced into a building, and at the same time dust, insects andparticles of foreign matter are excluded. Proper ventilation is alsopossible without leaving the doors or windows open, thereby enablingfresh Vair to be admitted to the house when all of the doors and windowsare locked to prevent entry by an unauthorized person.

lVhile certain preferred forms and embodiments of the invention havebeen shown on the drawings and described for illustrative purposes, itwill be understood that many modifications and changes can be made inthe details of construction without depart-- ing from the spirit of theinvention and all within the scope of the claims.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is:

1. A ventilator including an open ended casing, a removable panelfitting across the opening of the casing, a set of shutters mounted uponthe inner face of the panel, lugs projecting from opposed interior wallsof the casing, swinging arms carried by the panel and adapted to extendinto the casing so as to be swung into and out of engagement with thesaid lugs, and means for controlling the shutters.

2.
